As what describe in different 3GPP standards, cordless communication network equipment 155 operates as the role of subscriber unit (userelement) (UE), and therefore, Wireless Telecom Equipment 155 can be called as UE in this article.Be appreciated that Wireless Telecom Equipment 155 can adopt multi-form, such as mobile phone, panel computer, portable computer, laptop computer and desktop computer.Cellular radio Communication system 100 also supports the communication with the wireless terminal of other types.
As everyone knows, Wireless Telecom Equipment 155 can carry out online " surfing ", the data communication sending and receive such as Email, transmission and reception file and perform other data manipulations.In order to support internet access and other data, services, the different execution modes of Wireless Telecom Equipment 155 implement 3GPP high-speed packet access (HSPA) standard.HSPDA comprises High Speed Uplink Packet access (HSUPA) and high-speed downlink packet access (HSDPA), which defines channel and process (procedure) that many groups make it possible to carry out in up link and down link respectively high-speed packet data transmission.
Be derived from Wireless Telecom Equipment 155(and subscriber unit or UE) or transmit on transport channels from the packets of information (packet) that Wireless Telecom Equipment 155 is specified.These packets of information can carry voice, video or data.Transmission channel is mapped to the physical channel of physical layer.Physical channel can use the different channel code of orthogonal in code domain (orthogonal).The instruction (AI) of catching that the execution mode of Wireless Telecom Equipment 155 comprises for accessing in conjunction with high-speed packet detects logical one 65.The operation of AI detection logical one 65 will be described in further detail below, but first will provide the Brief Discussion of the channel usage of Wireless Telecom Equipment 155.
Fig. 2 shows the figure of transmission according to the Wireless Telecom Equipment 155 of some execution mode disclosed herein and physical channel usage.Wireless Telecom Equipment 155 can work under different mode and state.Under certain conditions, such as, CELL_FACH state, does not have DPCH to distribute to Wireless Telecom Equipment 155, on the contrary, gives tacit consent to public or shared transmission channel for ul transmissions.Common transport channel is called as enhancing dedicated channel (E-DCH) 205.As shown in Figure 2, utilizing before E-DCH205 transmits data in user plane, Wireless Telecom Equipment 155 carrys out request access E-DCH205 by first sending access lead (accesspreamble) 210 in uplink physical channel to base station 120, and wherein uplink physical channel is called as Physical Random Access Channel (PRACH) 215.Responsively, base station 120 sends instruction that whether this request be authorized to and about the configuration information of resource being distributed to Wireless Telecom Equipment 155 by base station 120 on the physical down link channel being called as AICH Acquisition Indication Channel (AICH) 220.These resources can comprise, such as, and power, time slot and code resource.Can from the common pool allocation of codes resource of code being assigned to E-DCH205.Then, Wireless Telecom Equipment 155 uses the resource of distributing to avoid conflict, and sends user data on E-DCH205 simultaneously.
More specifically, Wireless Telecom Equipment 255 carrys out request access E-DCH205 by sending access lead 210 at the access slot (accessslot) of the Stochastic choice of PRACH215.Base station 120 is replied with catching instruction (AI) at the corresponding access slot of AICH220.Base station 120 also sends the information for distributed transfer resource of encoding at the corresponding access slot of expansion AICH (E-AICH) 225.In some embodiments, this coded message comprises the index of predefine resource table.
AI detect logical one 65 process receive on AICH220 catch designation data, thus classification access request result.To describe in further detail below, AI detects logical one 65 and states that (declare) access request is represented the nondeterministic statement of neither positive acknowledgement also not Negative Acknowledgement by positive acknowledgement, Negative Acknowledgement or be in.If AI detects logical one 65 and states positive acknowledgement state, the miscellaneous part so in Wireless Telecom Equipment 155 can use the transfer resource of distribution to send user data on E-DCH205.Especially, if AI detects logical one 65 state positive acknowledgement state, the reflector power level so in Wireless Telecom Equipment 155 sends user data, and this power level is according to calculating for the level sending a upper access lead 210.
On the other hand, if AI detects logical one 65 state Negative Acknowledgement state, so the physical layer of Wireless Telecom Equipment 155 stops transmission and control is given back medium access control (MAC) layer.Wireless Telecom Equipment 155 finally regains access according to MAC program, and MAC program is by the 3GPP standard definition based on continuation probability.
If AI detects logical one 65 state nondeterministic statement, so to suppose that base station 120 does not receive leading for Wireless Telecom Equipment 155, and use open Loop Power control to send another access lead 210.
Should be appreciated that detection scheme has the probability P of certain error detection AI
fEAI.This error detection can cause distributed transfer resource of decoding improperly.(more specifically, the error detection of EAI causes the E-DCH resource configuration index of decoding error).The mistake utilizing incorrect transfer resource to cause again on the receiver when sending user data.Therefore, expect to reduce P
fEAI.
Compared with conventional art, utilize technology disclosed herein, AI detects logical one 65 and reduces P
fEAI.Traditional AI detection technique compares channel power and the threshold value of AI signature, and wherein this threshold value represents the total channel power of received AI signature.The execution mode that AI disclosed herein detects logical one 65 uses extra threshold value to compare, and this compares the degree of reiability (reliabilitymetric) relating to expansion AI.Depend on the result additionally compared, AI detects logical one 65 and states Negative Acknowledgement state or uncertain (non-declarative) state.Nondeterministic statement means that AI detects logical one 65 and can not to decode EAI.As mentioned above, by adjusting the power level of next access lead 210, the reflector in Wireless Telecom Equipment 155 is reacted to nondeterministic statement.
Wireless Telecom Equipment 155 comprises control logic, power control circuit, symbol decoder, transceiver and AI and detects logical one 65.As mentioned above, Wireless Telecom Equipment 155 receives the response to access request on AICH Acquisition Indication Channel (AICH) 220.The symbol decoding that AICH220 carries is become data by symbol decoder, and provides the data value of decoding to control logic.Symbol decoder is also for control logic provides the one or more parameters be associated with decoded data value.These parameters can comprise, such as, and the channel power of particular solution code value and the degree of reiability of particular solution code value.
Control logic provides the AICH data of decoding and described tolerance to detect logical one 65 to AI.AI detects the deployment (disposition) that logical one 65 the AICH data using decoding and the parameter be associated determine access request.Especially, AI detects logical one 65 operation parameter determination access request by positive acknowledgement, Negative Acknowledgement, be still in and represent neither confirm the nondeterministic statement also do not refused.AI detects logical one 65 and states that access request is in a state in these three states, and this comformed information is supplied to control logic.In some embodiments, determine two states, one for catching instruction (AI), one for extended acquisition instruction, wherein these two states are separate.
Control logic uses the state of access request to control the power of transceiver.More specifically, if determine that access request is nondeterministic statement (represents and neither confirm also not refuse), so control logic indicated horsepower control circuit is reduced to the power of transceiver.This can pass through such as to realize with under type: make control logic respond AI detection logical one 65 and nondeterministic statement detected and provide power ramping to input (powerrampinput) to power control circuit, wherein power ramping input causes increasing to the power of transceiver.
Fig. 3 shows and detects logical one 65(Fig. 1 according to the AI of some execution mode disclosed herein) the flow chart of operation.Or the flow chart of Fig. 3 can be considered as realizing the different step that AI detects the method that logical one 65 performs.The process of Fig. 3 can by AICH Acquisition Indication Channel (AICH) 220(Fig. 2) on receive data-triggered, this is again in response to Wireless Telecom Equipment 155(Fig. 1) produce to base station 120(Fig. 1) access request.
Start at square frame 305, AI detects logical one 65 and obtains the decoded data that AICH220 carries and the different parameters be associated with decoded data.As mentioned above, these data and parameter can directly be provided by symbol decoder or provide via control logic.Comprise in the AICH data of square frame 305 acquisition and catch instruction (AI), corresponding AI signature and one group of extended acquisition instruction (EAI).
In block 310, AI detects logical one 65 and checks the AI obtained at square frame 305, and determines that the AI corresponding to this AI signs.Then, AI detects channel power (also obtaining at square frame 305) and the first predefine limit that logical one 65 compares this AI signature.This first predefine limit represents the total channel power of received AI signature.In some embodiments, this gross power calculates the channel power summation of signing as the AI of all receptions.Power bias (poweroffset) can be passed through and determine (scale) this summation in proportion.In some embodiments, the first predefine limit used in block 310 corresponds to the T2 parameter described in 3GPP physical layer specification.
If determine that the channel power of received AI signature is no more than the negative value of the first predefine limit (such as in block 310, ﹣ T2), so AI detects logical one 65 and advances to square frame 315, will further compare the reliability considering EAI data in square frame 315 before the deployment determining access request.But if determine that the channel power of received AI signature is more than the first predefine limit (such as, T2) in block 310, so AI detects the deployment that logical one 65 determines access request, and does not consider EAI reliability.For this reason, AI detects logical one 65 and advances to square frame 320, wherein calculate acquiescence E-AICH resource index according to the information received on AICH220, then advance to square frame 325, wherein AI detects logical one 65 by statement AI is the deployment that access request is determined in positive acknowledgement (PositiveAcknowledgement).In some embodiments, the statement of positive acknowledgement equals numerical value+1.Make AI have statement value, the process of Fig. 3 terminates.
As mentioned above, if the channel power of the AI signature received is less than or equal to ﹣ T2, so AI detects logical one 65 and performs additionally comparing of the reliability considering the EAI data received.For this reason, detect logical one 65 calculate EAI confidence value at square frame 315, AI, this EAI confidence value is used in the ratio between the selected extended acquisition instruction of the extended acquisition instruction that square frame 305 obtains.In some embodiments, select the expansion AI with the highest absolute value and the second high absolute value, the ratio calculated at square frame 315 is like this abs(EAI_ the second height/EAI_max).Then, confidence value may be calculated and deducts this ratio (such as, 1.0 ﹣ ratios) from 1.0.
In square frame 330, AI detects logical one 65 and compares the EAI confidence value and another predefine limit (referred to herein as T3) that calculate at square frame 315.Rule of thumb can determine that this predefine limit T3 detects (falsepositivedetection) rate (P with the false positive realizing expecting to EAI
fEAI).Such as, different T3 values is utilized can to draw (plot) E
c-AICHwith I
orratio (with db), produce false positive and power use between the T3 accepting to trade off can be selected as the threshold confidence value of square frame 330.
If determine that the confidence ratio (calculating at square frame 315) of received EAI is less than T3 threshold value at square frame 330, so determine that the deployment of access request does not need to relate to comparing further of EAI data reliability.Therefore, process and proceed at square frame 335, wherein AI detects logical one 65 by statement AI is the uncertain deployment determining access request.In some embodiments, uncertain statement equals numerical value 0.Make AI have the value of statement, the process of Fig. 3 terminates.
If determine that the confidence ratio (calculating at square frame 315) of received EAI is more than or equal to T3 at square frame 330, so perform and relate to additionally comparing of EAI data reliability, thus determine the deployment of access request.For this reason, process and proceed at square frame 340, wherein consider the symbol with the EAI of maximum value (EAI_max).If EAI_max<0, so in square frame 345, AI detection logical one 65 is Negative Acknowledgement and EAI by statement AI is the deployment that access request is determined in positive acknowledgement.On the other hand, if EAI_max is more than or equal to 0, so in square frame 350, AI detection logical one 65 is Negative Acknowledgement and EAI by statement AI is the deployment that access request is determined in positive acknowledgement.Therefore, AI is set to Negative Acknowledgement and has nothing to do with EAI_max, but the symbol of EAI_max determines the setting of EAI.In some embodiments, Negative Acknowledgement can correspond to numerical value+1 corresponding to numerical value ﹣ 1 and positive acknowledgement.
In arbitrary situation, in square frame 355, AI detects logical one 65 and calculates E-DCH resource configuration index according to the information received on AICH220.Then, the process of Fig. 3 terminates.
